Our general interest e-newsletter keeps you up to date on a wide variety of health topics.
Your bone marrow makes blood cells, including red blood cells. Chemotherapy can damage your bone marrow. When this happens, your body makes fewer red blood cells or destroys them before their normal life span is over.
Your body's ability to produce platelets — a blood cell that plays an important role in forming clots — also may decrease, so you're more likely to bleed, further reducing your red blood cell levels.
Your red blood cells contain an iron protein called hemoglobin, which carries oxygen from your lungs to the rest of your body. Anemia means you have too little hemoglobin, so parts of your body aren't getting enough oxygen, which is why you feel tired and weak a lot.
Consider the following step to help manage your anemia.
Timothy J. Moynihan, M.D.
